Fashion bag maker Intel has released a new range of chips which are unlocked – something you normally only see on more expensive models.
The Pentium “Anniversary Edition” G3258, Core i5-4690K and Core i7-4790K, all have an unlocked clock multiplier and several tweaks to improve its overclocking potential.
Based around a Devil’s Canyon core, Chipzilla has changed its Thermal Interface Material (TIM) to Next-Generation Polymer TIM, or NGPTIM. It has also improved power by adding more capacitors.
The Pentium G3258 doesn’t have Devil’s Canyon enhancements, but it does have the clock multiplier unlocked which means that it is the cheapest unlocked chip available.
The i5-4690K and i7-4790K have 4 CPU cores, 6 or 8MB last level cache, and support for DDR3-1600 memory. The processors run Haswell instruction set extensions, including TSX. They cannot manage VT-d virtualization and Vpro features. The Core i5-4690K can’t manage Hyper-Threading but otherwise most of Haswell technologies are supported.
According to CPU world, both CPUs come with higher clock speeds. The i5-4690K runs at 3.5 GHz, or 100 MHz higher than the i5-4670K. Compared to the Core i7-4770K, the i7-4790K is 500 MHz faster.
Both Devil’s Canyon chips support Turbo Boost feature, and their maximum turbo frequency was increased by 100 MHz on the i5 part, and by 500 MHz on the Core i7-4790K. The i5-4690K and i7-4790K integrate HD 4600 graphics, clocked at up to 1.2 GHz and 1.25 GHz respectively. To allow higher clock speeds and better overclocking, the chips are rated at slightly higher than standard TDP, at 88 Watt.
The i5-4690K and i7-4790K are priced at $242 and $339. The CPUs should be available in stores in June.
The Pentium Anniversary Edition is rated at 53 Watt TDP. At $72, it is only $8 more expensive than the Pentium G3240.
